Colonial era migration During the colonial era, Orcadians have been documented migrating in search of opportunity.

Emigrants to London and York, England, also found inland posts related to the fur trade. According to ethnohistorian Jennifer S. H. Brown, "at least twenty-eight Orkneymen became either governors, chief factors, chief traders, or district master between the early 1700s and the mid-1800s".
